The act of browsing random MySpace pages and finding decently hot chicks, with decently hot pictures.
One then proceeds to jerk off to these said pictures.

*note*- said activity can also be applied to Facebook and a variety of other social networking sites, but due to the popularity, and low security settings, MySpace is preffered.

Kid 1- Hey dude so what'd you do last night?

Kid 2- Nothing much, just stayed home and did a little Browse and Jerk

Kid 1- Wtf is that?

Kid 2- it's when you click on Browse in MySpace, and change the settings to like, female, between the ages of 18-21, within 10 miles from my zip code, then you look for the really slutty ones and jerk off to their pics. Trust me, theres something about it that makes it better than porn.
